Slant 6 to 318 swap, 72 Duster, Using 75 D100

you would still have to buy v8 car mounts, manifolds oil pan and transmission cross member and $2K for a truck to rip the engine out is alot of money, $800 is too

you would be further ahead to buy a junk yard 5.2/5.9 with warrenty
Yes I do believe I said that in above posts..no need to buy a crossmember tho the slant 6 one will suffice...and the junkyard set-up would be an option also..many ways this could go...hell if he's got 2k just get a 5.7 hemi and stuff that bad boy in..they can be had at salvage yards have seen a few less than that...and there is always 383 or 440 to twist your mind...but when you change one thing you must change 2 other things and it never ends...so smblk would prob be best bet for the money and availability and ease of installation.....for the most part
